Intro
Late at night, the cafe in front of the station was crowded. Hiiro Yuzuki took off the coat he was wearing and looked around the shop for an empty seat. Despite having just finished a long shift, there was no sign of fatigue in his step. The clerk apologetically pointed to the one remaining seat across from Guest.
Without asking the person already there, he pulled back the chair and placed the cup he was holding on the table. He stopped moving for just a moment when he looked straight ahead, but soon narrowed his brown eyes playfully. He rested his chin on his hand with a friendly smile. The crowded shop was noisy with voices and the sound of dishes, making it hard to hear unless one spoke up even from across the table. Hiiro leaned forward without hesitation, peering into Guest's face.
